PSW-2/4 loudspeaker systems
Type 6 Products - This refers to MSL-6, MSL-5 and PSW-6
loudspeaker systems.
1. INTRODUCTION
2.THE MEYER SOUND QUICKFLY SYSTEM:DESCRIPTION AND ADVANTAGES
From the outset, Meyer Sound loudspeakers have offered a
variety of rigging and fittings to allow configuration into
larger multi-cabinet systems for either fixed installation or
touring rental applications. To provide further flexibility
and improved ease of set-up, Meyer Sound has introduced
the QuickFly system. QuickFly provides sound reinforcement professionals with a rigging/arraying system that is
safe, cost-effective and remarkably easy to use. QuickFly
can dramatically reduce system set-up and breakdown
times, and in some circumstances QuickFly's enhanced
arraying capability can improve overall system performance. The Meyer QuickFly system is currently designed to
integrate those Meyer Sound products most often used in
larger flown arrays. Further expansion of the QuickFly system's availability to incorporate other Meyer Sound products is anticipated in the near future.
As a flying system, Meyer Sound's QuickFly rigging is both
ingeniously simple and supremely flexible. It offers the
ability to integrate a number of different Meyer Sound
loudspeakers into accurate arrays and clusters ideally suited to the vast majority of fixed or touring requirements.
With QuickFly, arrays may be assembled quickly and configured at angles that take full advantage of the controlled directional characteristics of Meyer Sound products.
Exceptional flexibility in vertical angling usually eliminates the need for any pull-up points or strapping.
QuickFly also accommodates multiple horizontal splay
angles, from tight pack to optimum wide dispersion.
The QuickFly system is based on the standardized L-Track
hardware system. L-Track is widely employed in other situations, most notably in aircraft manufacture, but also in
many other situations calling for adjustable mechanical
mounting systems with a very high degree of tensile
strength and secure, fail-safe fitting mechanisms. In addition to the L-Track hardware affixed to the loudspeakers,
L-Track is an integral component of the various rigging
frames and grids that comprise the complete QuickFly system. Meyer Sound supplies a number of pre-configured
attachment devices that link directly to the loudspeakers
or that are custom-designed for determining specific
arraying characteristics. Many other attachment clips,
locks and other accessories for L-Track are supplied as part
of the system. Alternates are also widely available from
other suppliers; however, care should be taken that only
appropriate parts from reputable suppliers and are used.
(See Section 3.7)
Three primary design goals behind Meyer Sound's QuickFly
rigging system are based on safety and simplicity.
1. To transmit all load stresses through the metal rigging
structures and not through the wood cabinet panels.
This allows taller arrays of cabinets and adds confidence to those using the system (See Figure 1 on the
following page).
2. To eliminate the need to place a worker’s hands
between cabinets when assembling a flown system.
This speeds up the rigging process greatly reduces the
possibility of worker injury.
3. To create a system that is safe.
MSL-4 and DS-4P cabinets equipped with the L-Track
option utilize four full length pieces of stainless steel as
load-bearing elements. We also offer a retrofit kit for cabinets not equipped with the L-Track option.
All Meyer Sound loudspeaker cabinets have internal, metal-fabricated bracing structures to which flying points (in
this case the external L-Track strips) are secured. When
loudspeakers are flown, all forces are carried through the
track and the internal bracing structure keeping strain

3. RIGGING OVERVIEW AND SAFETY ISSUES
3.1 IMPORTANT NOTICE TO QUICKFLY OWNERS AND
USERS
PLEASE READ THIS SECTION CAREFULLY AND IN ITS
ENTIRETY. IT CONTAINS CRITICAL INFORMATION REGARDING SAFETY ISSUES, INCLUDING GUIDELINES FOR GENERAL
SAFE USE OF RIGGING SYSTEMS AS WELL AS ADVISORIES
ON GOVERNMENT REGULATIONS AND LIABILITY LAWS. MEYER SOUND CANNOT BE HELD RESPONSIBLE FOR CONSEQUENCES THAT MAY ENSUE DUE TO FAILURE TO READ AND
COMPLY WITH INFORMATION IN THIS SECTION.
3.2 SCOPE OF THIS MANUAL
Although this manual contains much useful information
on rigging in general, it does not claim to be a comprehensive resource on the subject. This manual assumes that
the owners and/or users of a QuickFly system are knowledgeable and experienced in the areas of rigging and flying loudspeaker systems. Many issues of crucial concern,
such as the determination of appropriateness and condition of venue rigging points, cannot be addressed here.
Therefore, the user must assume all responsibility as to
the appropriate use of the QuickFly system in any particular location or circumstance.
The suspension of large, heavy objects in public places is
subject to numerous laws and regulations at the national/federal, state/provincial and local levels. This manual
does not address the specifics of any such applicable laws
and government regulations. This manual details proce-
dures and practices consistent with those generally
acknowledged as allowable and safe in the United States.
However, the user must assume responsibility for making
sure that use of the QuickFly system and its components
in any particular circumstance or venue conforms to all
applicable laws and regulations in force at the time.
3.3 L
OAD RATINGS AND SPECIFICATIONS
Long-term safe operation is a central concern in the
design and manufacture of any rigging/flying system.
Meyer Sound has taken great care in material selection
and component design. In all critical cases, load points
are redundant, with a safety margin that allows one or
more load points to fail and still maintain system integrity. After manufacture, all load-critical system components
are individually inspected.
All load ratings and other specifications given in this
manual are the result of accepted engineering practice
and careful testing. However, such specifications and ratings are subject to change. Users are advised to check the
QuickFly section of the Meyer Sound web site (or contact
Meyer Sound Technical Support) at regular intervals to
check for updated or revised information.
3.4 R
EGULATORY COMPLIANCE
The engineering practices and Safe Working Load (SWL)
ratings of the QuickFly system are in full compliance with
all known regulatory statutes currently applicable in the
away from the wooden cabinet. L-Track-equipped cabinets,
in use with an MTG-4 top grid or MRF-6 rigging frame,
ensure that an almost straight pull exists through the LTrack and connection fittings in a column of flown loudspeakers. An MTG-4-based system is illustrated in the following figure (Figure 1).
The same principle applies to an MRF-6 rigging frame
when mounted onto a Type 6 loudspeaker: the load
stresses travel through the internal steel framework of the
loudspeaker, bypassing the wood panels of the cabinets.
The MRF-6 is bolted directly onto the steel frame (both
top and bottom) of the Type 6 cabinet.
In addition, QuickFly is designed to allow assembly of
arrays without placing hands between the cabinets. All LTrack connections made between frames and/or Type 6
and Type 4 cabinets are accomplished in front of or
behind the loudspeaker. The only exception is when an
MTG-4 Rigging grid is attached to the bottom of a Type 6
array. However, in these cases, a greater space between
cabinets will provide an increased safety margin.
Please review the operating instructions that accompanied
the particular loudspeaker cabinets used in the system for
information on enclosure dimensions and rigging track
locations.

United States. All working loads are based on a 5:1 safety
factor.
However, as noted above, there are wide variations internationally in the regulations and practices applying to suspension of sound systems in public places. Although regulations in the USA are generally among the most stringent,
safety codes may be even stricter in a few localities (such
as those highly prone to earthquakes). In addition, applicable safety codes are open to interpretation: government
officials in one location may have a stricter interpretation
than officials in other locations, even when operating under
the same regulations and in the same legal jurisdiction.
Consequently, users of QuickFly should be prepared to take
additional safety assurance measures beyond those outlined in this manual. In all cases, it is the sole and express
responsibility of the user to make certain that any Meyer
Sound loudspeaker system is suspended in accordance with
all applicable national, state/provincial and local regulations.
3.5 ADVISORY NOTE: SAFETY RESPONSIBILITIES OPEN TO
INTERPRETATION
In most touring applications of rigging systems, the touring sound provider is normally responsible only for ensuring the safety of the suspension system below the attachment point. The safety and suitability of the attachment
point is generally seen as the responsibility of the venue
owner or operator. However, this distinction ("above the
hook" versus "below the hook") may be open to interpretation. Touring system operators would be well advised to
double check to make certain that attachment points are
approved and suitably load rated, and that the points used
are those identified as such by the venue owner or operator. As an extra precaution, careful inspection of the
attachment points is advised before flying, particularly in
older venues or those hosting frequent events using large
sound and lighting systems. In any case, Meyer Sound
QuickFly systems are intended only for suspension from
approved rigging points, each known to have ample SWL
margins for the system components suspended below them.
3.6 INSPECTION AND MAINTENANCE
The Meyer Sound QuickFly system is an assembly of
mechanical devices, and is therefore subject to wear and
tear over prolonged use, as well as damage from corrosive
agents, extreme impact or inappropriate use.
Because of the safety issues involved, users must adopt
and adhere to a schedule of regular inspection and maintenance. In touring applications, key components must be
inspected before each use. Such inspection will include
examination of all load-bearing components for any sign of
undue wear, twisting, buckling, cracking, rusting or other
corrosion. In regard to rust and corrosion, all main components of the QuickFly system are either protected by an
exterior coating or are made from stainless steel, which is
impervious to rust and resistant to most corrosive fluids.
Nevertheless, normal use and shipping vibrations can wear
through the protective coatings, and extremely corrosive
fluids (such as battery acid) can cause severe damage with
prolonged exposure even to protected parts. Particular
attention should be given to screws, bolts and other fasteners to make certain the fittings are tight and secure.
Metal seams and welds should be examined for any sign of
separation or deformation. Meyer Sound strongly recommends that written documentation be maintained on each
QuickFly system, noting date of inspection, name of
inspector, points of system checked, and any anomalies
discovered.
In addition to routine checks on the road for touring systems, Meyer Sound also recommends a careful, comprehensive system examination and testing "at home" in the
warehouse or other appropriate location at regular intervals. At this time, each component should be carefully
inspected under ideal lighting conditions, and then the
entire system should be flown as used for a final comprehensive check.
If any anomalies or defects are discovered that could possibly affect the safety or integrity of the system, any
affected parts or subsystems should be replaced in their
entirety before that part of the system is flown again. (See
3.7 below.)
3.7 REPLACEMENT PARTS
Any component found to be defective, or any safety-related
component you even suspect might be defective, should be
replaced with the equivalent, approved part. In the case of
parts specific to the QuickFly system, these parts should be
ordered directly from Meyer Sound. No attempt should be
made to substitute what appear to be equivalent or "mostly the same" generic replacements.
Many other parts used in a QuickFly system will be identical to those used in other L-Track applications. To the best
of our knowledge, all suppliers of L-Track components are
reputable and their products reliable. However, Meyer
Sound has no way of assuring the quality of products made
by these various suppliers. Therefore, Meyer Sound cannot
be held responsible for any problems caused by components that were not supplied by Meyer Sound.
3.8 TRAINING
Considering its sophistication and flexibility, the QuickFly system is relatively straightforward and easy to use. Nevertheless,
there are key points of assembly, rigging and flying that must
be fully mastered before a system is flown. Users should read
this manual in its entirety before attempting to deploy a
QuickFly system. (You may make additional photocopies of
this manual as necessary for in-house training purposes only;
please do not distribute outside your company.)

4.0 MRF-6 RIGGING FRAME PART NO.40.053.048.01
3.9 OWNER RESPONSIBILITY AND LIABILITY EXPOSURE
Flying and rigging systems are unique in the sound reinforcement industry in that misuse, improper deployment
or failure of key components could lead to significant
property damage, injury or loss of life.
At Meyer Sound, we have gone to great lengths to preclude any possibility of critical component failure under
normal use and within a reasonable program of preventive
maintenance. All QuickFly system parts are engineered to
provide ample safety margins for load bearing, torsional
stress and impact. Suggested system configurations have
been thoroughly tested for stability and balance using
computer modeling and extensive field-testing. Each production component is carefully inspected before shipment
to the customer, and each crucial part is identified to
trace and isolate any potential problems.
Nevertheless, the Meyer Sound QuickFly system is not, if
you will pardon the expression, "idiot proof." Although we
have tried to account for oversight in the field (improper
or incomplete assembly) and possible misuse (flying too
many loudspeakers from a frame), it is unreasonable to
assume that a key component failure will never occur
under any circumstances.
Consequently, is it the express responsibility of the user to
ensure that the QuickFly system is deployed in strict
accordance with the strength ratings, rigging techniques
and other precautionary advisories given in this manual
and in any manual updates. Additionally, the user is also
solely responsible for ensuring that the Meyer Sound
QuickFly system is deployed in accordance with all applicable government safety regulations.

4.1 OVERVIEW
The MRF-6 is primarily used for horizontal and vertical
arraying of Type 6 products. Additionally, the MRF-6 incorporates L-Track horizontally mounted on the frame for suspension below of L-Track equipped cabinets (or those utilizing the RFK-1 retrofit kit). Using the MRFCB-6 connecting bar kit, multiple MRF-6 frames can be vertically
arrayed with splay angles from 0° to 10°. Horn coupled
long throw arraying can easily be achieved (Figure 2) to
allow for variations in narrow coverage control. The MRF-6
also accommodates basic horn up/horn up arraying as well
as attachment of MSL-6s to PSW-6 subwoofers. The MRF-6
easily retrofits to new or existing products.
4.2 K
IT CONTENTS
The MRF-6 kit contains the welded frame assembly and all
the hardware necessary to attach the frame to a cabinet
and to secure two frames side-by-side. The frame itself is
a welded 6061-T6-aluminum construction. Four sections of
heavy-duty aluminum L-Track are attached to the frame.
Grade 8 bolts and washers are provided to attach the
frame to the Type 6 loudspeaker cabinet. Split ring lock
washers and sealant are included as well. Two 3/4" bolts
with nuts and washers are provided for securing two
frames together horizontally by bolting through the side
plates of the frame assembly.

4.3 SIMPLE SYSTEM EXAMPLES
Figure 2, above, shows four MSL-6 cabinets flown in a configuration that will give 60 degrees horizontal coverage by
13 degrees vertical coverage. Figures 7 and 8 on Page 8
show two Type 4 loudspeakers attached to the Type 6 MSL6 via 8 SLC-1 connecting chains. Each MSL-6 is fitted with
an MRF-6 rigging frame on its top and bottom. The MRF-6
is attached to the lifting motor set via a 5/8" (or larger)
shackle through one of the lifting points located along its
central structural member.
4.4 ATTACHING THE MRF-6 TO A TYPE 6 PRODUCT
The MRF-6 rigging frame attaches to a Type 6 loudspeaker's
internal steel rigging structure (See Section 4.5) through
the cabinet’s existing rigging attachment points. Tools
required are a ratchet with a 1/4" allen bit and a 1/2"
socket, and a caulking gun. This procedure takes 20 to 30
minutes. Using the 1/4" allen bit, remove all six of the
existing pivoting lifting rings from the cabinet. (Figure 3)
The rings will be replaced; set them nearby.
Using a caulking gun, place a small amount of silicone
evenly over each hole just prior to positioning the frame
onto the cabinet (Figure 3).
Note: The holes must be resealed using the included
silicone sealant (GE IS800 series) to avoid creating air leaks from the cabinet's airtight chambers.
Immediately after applying the silicone, return the triangle
rings and the round blocks to their proper places on the
cabinet. Be careful to position them over the mounting
holes so that the thread path of each mounting bolt
remains unobstructed. Place the MRF-6 aluminum frame on
the cabinet, positioning it over the mounting holes (Figure
4). Be careful not to change the position of the rings and
round blocks.
Using a 1/2" socket and the hardware provided, attach the
MRF-6 to the cabinet (Figure 5).
Alignment with all twelve holes on the cabinet is easiest if
you start by first hand-tightening the bolts through the
front inner lifting rings, proceeding next to the rear lifting
ring locations and finish with the front outer locations.
Once the bolts are hand-tightened, torque each of them
down as evenly as possible to avoid any possible damage
to the cabinet. The bolts should be torqued to 10-20 ftlbs. Care should be taken to avoid cross threading or overtightening the bolts. Although locking washers are used,
the bolts always should be inspected prior to use in a
flown system. Ensure that all bolts are properly tightened
and evenly secure the frame to the cabinet.

An MRF-6 may be fitted only on the top of the enclosure
if other loudspeaker systems will be suspended below
using the standard pivoting lifting rings (Figure 6).
Frames should be fitted to both the top and bottom of
the enclosure in all configurations where loudspeakers
will be suspended below using the front and rear horizontally mounted L-Track. Further Type 6 loudspeaker
systems may be mounted in this manner, or you may
transition to Type 4 enclosures via a directly mounted
MTG-4 or the TGSB-4 Spreader Bar transitioning to two
MTG-4 top grids.
